One of the most surprising powers that Glimmer demonstrated was her ability to fly as witnessed in the season two She-Ra episodes "Return Of The General" and "Portrait of Doom".

It was never explained how Glimmer whose ability to control light could fly. As with her rarely used teleportation powers her ability to fly would have gotten her out of many a dangerous situation...
